ProBook 6570b

I have a ProBook 6570b which I earlier had Linux Mint and Zorin OS 16.3 installed, then I switched to Windows 10. Now I want till install Zorin again but I can't get it working. After reboot I got the message no bootable device was found, I tried to change various BIOS settings but seem to have messed it up. 
So what are the recommended settings for this machine? I've googled and find contradictory opinions. 
Also, I've tried to restore to factory default (also security settings) but apperantly not all values will be restored - just some of them - is there something I've missed?
